Both Medicare and Medicaid have national “medically unlikely edits” (MUEs) in place that are designed to automatically deny claims that exceed specific daily limits. Although these MUEs have been in place for some time, some Medicaid plans are only now beginning to implement them. MUEs should not be confused with annual utilization limits that we have seen from many commercial payers.
For many years, the MUEs were confidential and were not published. But a couple of years ago, CMS decided they should be made publically available. Although we have published them before and they have not changed, we thought this would be a good time for a reminder.

For example, if you bill Medicare or Medicaid for more than 80 skin tests on a given day, you may receive a denial. Likewise, a claim with more than 30 doses of allergen immunotherapy (95165) may also trigger a denial. You may want to be aware of these limits when billing Medicare and Medicaid.
It is also important to remember that, for payment purposes, Medicare defines a dose of allergen immunotherapy as one cc of extract. Because Medicaid is a state program, policies vary from state to state. If your state Medicaid plan adopts the same policy on definition of a dose as Medicare, the Advocacy Council may be able to provide guidance for a discussion with Medicaid payers.
